I have tried to glaze a terracotta clay bust that I made but the glazing went wrong (irregular coating and covering)
and I would like to know if it can be de-glazed or sanded so that I can paint it.
thank in advance.

Dear Yamina,

    Thank you for your recent question. Yes, you can re-glaze the piece by following these instructions:

    1. Using 800 grit sandpaper, sand the entire piece to break the smooth coating of the glaze and help create a surface prepared for re-glazing. You do not need to sand the glaze off, however, the surface must not feel completely smooth. If you see white dust as you are sanding, you are sanding correctly. Be sure and wear a mask to protect your lungs.

    2. To each 500 grams of glaze, add 2 tsps full of honey and 1 tsp of vinegar. Mix very well.

    3. Apply the glaze to the sculpture. To assure even coverage, work with downward strokes for the first coat, horizontal strokes for the second coat and downward strokes for the third coat. Just to note, terracotta is a highly porous clay body. If it is being glazed with one glaze color over the entire piece, I suggest you dip the piece in the glaze. Otherwise, increase the coatings to 5 layers, making sure the glaze dries between each layer applied.

    4. Fire your sculpture to maturing cone.

    I hope this has answered your question. Please feel free to contact me anytime in the future if you have further questions or need further assistance with any pottery related issue. I am always at your service. Good luck.
